Method for performing integrated biomass overpressure fixed bed gasification of steam turbine in power plant, involves carrying out regenerative heating of low temperature deaerator, and filtering dust from hot generator gases
Method for performing integrated biomass overpressure fixed bed gasification of steam turbine in power plant, involves carrying out regenerative heating of low temperature deaerator, and filtering dust from hot generator gases
The method involves inputting biomass (1) over a pressure lock (2) into a low temperature deaerator (5). The gasification of fixed charcoal (7) is performed for thermally dividing long-chained pyrolysis gases (6) in a charcoal fixed bed gasifier (8) with descending gasification. The regenerative heating of low temperature deaerator is carried out with sensible heat of generator gas (9) and without cooling down generator gas. The dust is filtered from hot generator gases and incineration of dust free hot gas (12) is carried out in combustion chamber of a gas turbine. An independent claim is included for biomass overpressure fixed bed gasifier.
